Hi i am Robert
I juste looks at the first letter of your email ,it about the Mark 12d first check if you have good electrical connection in your airplane , you can take another mark 12d an put. It instead of your if it work well into the other airplane an has some
problem in yours then you know where to start . It's your airplane your your radio this is one way to solve part of it.
